A term consistently used during the lead-in to the "Twitters, Tweets and E-Mail" section of Craig Ferguson's "Late Late Night Show" on CBS.

May refer to the practice of setting a cell phone to "ring" not with sound but with vibration. Worn on the fanny (or inside a fanny pack), such a phone would be communicating an inbound call in "Ass Mode."

An intentional series of behaviors or statements by a disgruntled employee designed to harass the employer with out reaching a level that would result in the justified termination of the employee.

Ass Mode was first seen on the CBS "Late Late Show" with Craig Ferguson. Where Craig often say's something that is not politically correct or controversial ad will end the statement with the CBS catch phrase "CBS Cares" This behavior has also been seen on the "David Letterman Show" when Dave will say things about GE which owns CBS.

Craig will sometimes tell the audience that the show is running in ass mode because CBS is so cheap that the lighting hasn't been fixed, or a graphic was reused by crossing out part of it and crudely drawing in the new material
